Study Notes
Bitewing Imaging Devices
- Hawe-Neos Kwikbite: Simple yellow device for positioning with a ring aiming device (Kerr).
- Rinn XCP holder: Includes attachments for horizontal and vertical bitewings, optimized for dental imaging (Dentsply, USA).
- FASTab Bitewing Holders: Adhesive tabs for secure placement of bitewing films (Dentsply).
- Hager Emmenix Flap Foam Tabs: Designed for easy use in bitewing imaging (Hager Worldwide, USA).
- Rayvue Bitewing Holder: Another option for positioning during imaging (Vista Dental Products, USA).
Ideal Bitewing Characteristics
- Ideal Vertical Bitewings: Should capture the distal surfaces of primary canines and primary molars, along with the mesial surface of the first permanent molars.
- Phosphor Plate Sizes: Size 0 or 1 is preferred for primary dentition; Size 2 is better suited for late mixed dentition.
Sensor Positioning Techniques
-
Horizontal vs. Vertical Positioning:
- Size 0 or 1 sensors can miss information in horizontal orientation; vertical placement is preferable.
- Vertical orientation is less intrusive for young children, minimizing discomfort by being narrower.
- Mixed Dentition Considerations: Technique can be applied but may limit visualization of the first permanent molar.
Imaging Technology and Radiation Dose
- Image Receptor Speed: F-speed film recommended over D-speed film, reducing exposure doses by 60%.
- Digital Intraoral Radiography: Benefits include lower radiation doses compared to conventional films, with photo-stimulable phosphor plates (PSP) reducing dose by over 30%.
- Challenges with CCD Sensors: These sensors' thickness and cable positioning make them difficult for young children.
Summary of Imaging Improvements
- Technological advancements in bitewing imaging reduce radiation exposure significantly while enhancing the quality of diagnostic images in pediatric dentistry.
